Hi Josch, Kevin,

When you're in the Toolbar dialog, you'll also perhaps notice that a hotkey
is already assigned to the function of toggling the center crosshair. If you
hit the '5' on the numeric keypad, the crosshair will toggle.

_Or_, you can use Display... Ticks, Grids, Etc... Central Crosshair, and
turn the crosshair on, and/or select its color.

Undocumented feature: you can also change the symbol used for the crosshair.
For example, if you edit 'guide.dat' and add this line:

XHAIR_SYMBOL=e0,0,20;m-60,0;l-30,0;m60,0;l30,0;m0,60;l0,30;m0,-60;l0,-30;

Guide will show a circle with four lines radiating from it at the center of
the chart. The symbol format is described at

http://www.projectpluto.com/tdf_info.htm#custom_symbol

so you can customize the crosshair symbol (and some other symbols in Guide).
